WhoFi: New surveillance technology can track people by how they disrupt Wi-Fi signals

Hi-tech surveillance technologies are a double-edged sword. On the one hand, you want sophisticated devices to detect suspicious behavior and alert authorities. But on the other, there is the need to protect individual privacy. Balancing public safety and personal freedoms is an ongoing challenge for innovators and policymakers.

This New Tracking System Can Use Just Wi-Fi Signals to Identify You

Who-Fi is a cutting-edge technology that leverages artificial intelligence (AI) to identify and track individuals without needing any visual input. It is an experimental technology which remains to be thoroughly tested in the real world. However, based on the research paper that mentions and documents its proof-of-concept, it can be used to turn any ordinary Wi-Fi signal into a biometric scanner.

Wi-Fi Signal Patterns Can Identify People in Motion, No Camera Required

Researchers have developed a system that recognizes individuals by how their bodies distort Wi-Fi signals. It doesn’t use cameras. It doesn’t require visual data or physical contact. It listens to how wireless waves behave when someone walks by. The idea is simple. Wireless signals bounce, bend, and shift when passing through the human body. These changes aren’t random. They follow patterns shaped by body size, movement, and internal structure. …
